Value Collection 1-EFT-10-M7- Iron Thumb Screw 3/8-16

Product Description

The VALUE COLLECTION 1-EFT-10-M7- is an iron winged thumb screw designed for hand-tightened fastening applications where tools are not required. Built to a 3/8-16 UNC thread standard, it features a 3-inch length under the head and an overall length of 3-7/8 inches. The winged head style allows for firm finger-grip tightening and loosening, making it well suited for assemblies that require frequent adjustment or removal. This screw includes a shoulder, with a shoulder diameter of 5/8 inches, which helps with alignment and load distribution in the joint. The uncoated iron construction keeps it lightweight at 0.12 pounds per piece.

This thumb screw is commonly used in light industrial, mechanical, and shop-floor assembly applications where hand-operated fastening is preferred. The 3/8-16 UNC thread fits a wide range of tapped holes found in fixtures, jigs, guards, panels, and enclosures. It is appropriate for both original equipment assembly and maintenance or repair scenarios in trade and industrial environments. The winged head with shoulder design is a standard configuration used by machinists, maintenance technicians, and assembly workers across manufacturing and fabrication settings.
